.Parentodinium africanum was observed in rumen contents of four Brazilian cattle and constituted 4.4, 0.9, > 0.1, and 10.0% of the total ciliates. This appears to be the first observation of the family Cycloposthiidae in the rumen habitat. Blepharoconus krugerensis , previously observed in the intestines of the elephant, and an unknown species of ciliate with many characteristics similar to the family Paraisotrichidae were each observed in a single animal. A new subspecies, Diplodinium flabellum laterospinatum n. subsp., is also described. Total number of ciliates per ml of rumen contents ranged from 9.0 to 51.2 × 10 4 and included an overall total of 55 species and 4 subspecies.
